If you've got this combo, preferably a non step hull, could you please take a look at your aft drive ram pin and tell me which position its in (I.e. pin to the stern spacer towards bow, or vice versa)? This can be observed by looking at the ram ends in comparison with the oblong boss on the drive unit.

I just finished a gimbal bearing/bellows job and noticed the Mercrusier manual specifies that Bravo Ones should have the semi circular spacer positioned towards the bow, mine was in the opposite position which Merc states is for Bravo 2 and 3 only.

I can't tell if Donzi set it this way on purpose or if a prior servicer swapped positions unknowingly.

Thanks

OK , you've got me scratching my head now . I admit that as far as I recall mine (on a B3) has always been 'to the stern' , not the bow , but if it is designed to have a function how is that function different on different drives ?

If someone can answer this in a convincing manner I'm hoping that it will be one of the guys I consider 'know its' , not know it alls . :kingme:

From what I can tell the position of the spacer limits how far in the drive can be trimmed with the rams bottomed out. Going by the service manual, it appears Merc allows Bravo Ones to trim in further than Twos or Threes for whatever reason.

If your spacer is positioned in the stern position (I.e. your trim pin is closest to the bow), then your setup matches the merc manual recommendation for a B3.

Bravo 1 is forward.

I think its more to limit fully extended up so it stops before the gimbal.

The "celery stalk" spacer goes forward of the pin on a Bravo and Bravo 2 and to the rear of a Bravo 3 according to my mechanic I just called. This allows the drive to trim a little further down with the Bravo and B2 for quicker planing.

That makes sense 'cause there sure isn't any problem getting on plane with a B3

Thanks for the replys all, glad I noticed this and corrected it. My holeshot does seem considerably better now.
